Can reception be concentrated by infrared light receiver 132 after reflection, reduce the loss of reflection infrared light to greatest extent, so that it is guaranteed that
The accuracy of measurement result.Specifically, the LED infrared discharge lamps of PWM controls, infrared light can be used in infrared transmitter 131
The common infrared receiving tube of the prior art can be used in receiver 132.
Further, the fixed shell in above-described embodiment includes enclosure body and is located in enclosure body to pass for fixed
The sensor support body of sensor ontology；Sensor support body is cavity body, and sensor body is removably located in cavity body；Shell
Body ontology includes hat shape pedestal 21 and the seal cover board 22 being detachably connected with hat shape pedestal 21；Wherein, it is set in hat shape pedestal 21
It is useful for the first supporter 211 of support cavity body；Seal cover board 22 is equipped with the second supporter 221,211 He of the first supporter
Second supporter 221 is used to coordinate fixed cavity body.In addition, harness cable hole 222 is additionally provided on seal cover board 22.
During specific implementation, the structure of above-mentioned cavity body is varied, in order to make it easy to understand, the present embodiment is exemplary
Provide a kind of concrete structure：
Cavity body includes cavity body ontology and the cavity body cover board being detachably connected, in the process of installation sensor body
In, sensor body can be positioned in corresponding cavity body ontology, then pass through the clamping engagement of cavity body cover board so that passed
Sensor ontology is firmly fixed in cavity body ontology, and then cavity body is placed on the first supporter 211, makes first
Support body 211 is contacted with the bottom surface of cavity body ontology, followed by the clamping engagement of seal cover board 22, makes the second of seal cover board 22
Supporter 221 resists cavity body cover board, can by the interference fit of the first supporter 211, cavity body and the second supporter 221
Cavity body is firmly fixed.
By above-mentioned implementation process it is found that cavity body uses above-mentioned dismountable setting structure, can be sent out in sensor body
During raw failure, only replaced to being arranged on the intrinsic sensor body of cavity body, and it can be used repeatedly for other component, section
About maintenance cost.In addition, since the first supporter 211, cavity body and the second supporter 221 are using interference fit, a side
Face realizes the detachable of cavity body and replaces, and on the other hand ensure that the fixed fastness of cavity body, avoids due to sky
Cavity because fixed fastness is bad, and cause cavity body fix dislocation the occurrence of, further ensure reflection it is infrared
The accuracy of light measurement result.And in order to promote the leakproofness of fixed shell and preferably realize interference fit, this implementation
Cavity body and enclosure body in example may be used elastic material and be made, such as ethylene propylene diene rubber.
Further, it please refers to Fig.1 and Fig. 2, the hat shape pedestal 21 in above-described embodiment includes cap ontology and along cap ontology

212.The axis of intake tunnel 212 and 213 coplanar setting of mounting hole, intake tunnel 212 and cap ontology is in 45 degree of angles.
During practical operation, the present embodiment not setting to the setting quantity of intake tunnel 212 and mounting hole 213
Quantity is defined, illustratively, referring to Fig. 4,3 mounting holes 213 of setting and 3 intake tunnels 212, and intake tunnel
212 installation position is corresponding with the position of infrared transceiver module 13, is compared to intake tunnel 212 being arranged to an angle of 90 degrees
(perpendicular to the ground), in the present embodiment intake tunnel 212 set in 45 degree of angles can the rainwater that is accidentally splashed into of stop portions enter
In fixed shell, 11 erroneous judgement of data processor is avoided to there is water immersion, and then promote the accuracy for having water to immerse judging result.
It is worth noting that, automobile can stop powering to vehicle mounted electrical apparatus after overboard if vehicular power-bottle water inlet, accordingly
Onboard safety systems also can because power-off can not start, can bring inconvenience to the escape of occupant in this way, such as：Electricity
Motor-car window can not be opened after a loss of power, and in order to avoid the generation of the above situation, the mode that the present embodiment is threadably secured will
Above-mentioned automobile-used water sensor component is fixed on automobile storage battery position hereinafter, for example, on automobile chassis, can make automobile-used water logging in this way
Sensor module output immersion can judge signal before vehicular power-bottle is intake, and ensure that occupant can adopt at the first time
It is derived from the measure of rescuing.In addition, during automobile-used water sensor component is installed, it should be by 212 place plane setting of intake tunnel
Into accuracy parallel to the ground, being detected with raising immersion.
Preferably, the hat shape pedestal 21 in above-described embodiment, which further includes, is located at the intrinsic filter screen of cap, filter screen covering
Above-mentioned intake tunnel 212.By the setting of filter screen, the contaminant filter being mingled in the immersion in fixed shell can will be entered
Fall, impurity is avoided to impact reflection infrared light, ensures the accuracy of reflection infrared light measurement result, and then is improved
The accuracy for judging result of soaking.
You need to add is that referring to Fig. 2, this segment space of intake tunnel 212 to cavity body commonly known as holds water
Area 214, only when full appearance pool 214 is gushed in immersion, immersion could come into full contact with reflective glass 16, in this way, exiting infrared light
Line parameter of reflection infrared light for being formed after the reflection of reflective glass 16 can just vary widely to get to absolute difference
It is bigger；And hold pool 214 height setting it is higher, then it is then more long to gush the full used time for holding pool 214 for immersion so that from there is water logging
Enter state has the used time of water immersion judging result then longer to data pick-up output, that is, has the sensitivity that water immerses detection to get over
It is low；On the contrary, holding the lower of the height setting in pool 214, then there is water to immerse the sensitivity detected higher；By in this present embodiment
The setting height for holding pool 214 is roughly equal to the height of the first supporter 211, therefore, by adjusting the height of the first supporter 211
The i.e. adjustable sensitivity for thering is water to immerse detection, and data pick-up is caused to be mistaken for water immersion in order to avoid rainwater is splashed into
It happens, illustratively, the height of the first supporter 211 is set as 10mm.
